Description

Technical Field

[0001] This utility model relates to the field of solid-liquid filtration and separation technology, specifically a liquid continuous filtration and separation device. Background Technology

[0002] In industrial production fields such as chemical engineering, food processing, and water treatment, liquid filtration and separation are core routine processes that ensure the quality of subsequent processes, achieve material recovery, and ensure that wastewater meets discharge standards. The core objective of this process is to separate solid particles or suspended matter from the liquid through physical interception, thereby purifying the liquid and meeting the purity requirements of the production process.

[0003] Currently, most existing liquid filtration and separation methods utilize filter screens placed in pipelines or filtration tanks to intercept solid impurities in the flowing liquid, achieving effective separation of liquid and solids. However, during the filtration process, the intercepted solids or suspended matter continuously accumulate on the surface of the filter screen and cannot be automatically discharged. This necessitates periodic shutdowns by staff to manually clean or replace the filter components. This process is not only cumbersome and labor-intensive but also forces interruptions in the filtration process, severely impacting overall production efficiency. Furthermore, as the amount of solid matter deposits increases, the effective flow area of ​​the filter screen gradually decreases, easily leading to filter clogging. This results in increased filtration resistance, decreased liquid flow rate, and ultimately, reduced filtration efficiency. Utility Model Content

[0004] Therefore, to address the shortcomings mentioned above, this utility model provides a continuous liquid filtration and separation device. This device, through a filter screen plate arranged at an incline within the separation tank, can effectively intercept solids or suspended matter in the liquid. Simultaneously, combined with a cleaning mechanism on the filter screen plate's surface, the filter screen plate can be cleaned promptly during the filtration process, scraping solids or suspended matter upwards from its surface to prevent accumulation and blockage, thus maintaining filtration efficiency. Furthermore, a slag discharge trough plate on the outer side of the discharge end of the cleaning mechanism can collect and discharge the scraped solids or suspended matter, preventing them from flowing back into the separation tank. This achieves effective filtration, separation, and discharge of liquid and solids, forming a continuous filtration and separation process.

[0005] This utility model is implemented as follows: a continuous liquid filtration and separation device includes a separation tank, with an inlet pipe connected to the bottom of one end and a drain pipe connected to the bottom of the other end. The filter screen is inclined and in contact with the bottom of the separation tank. The cleaning mechanism rotates and is located at the outer end of the filter surface of the filter screen plate while maintaining its top extension above the separation tank. The slag discharge trough plate is set on the outside of the discharge end of the cleaning mechanism and fixed on the separation tank.

[0006] Preferably, the cleaning mechanism includes a rotating rod that is rotatably mounted on the inner wall of the separation tank and parallel to the top of the separation tank. A transmission belt is sleeved on the outer end of the rotating rod. Several support plates are evenly spaced on the outer end of the transmission belt. The outer end of the support plates is close to the filter screen plate. Filter holes are evenly opened on the support plates.

[0007] Preferably, a support base is fixed above the wall of the separation tank, and the rotating rod passes through the support base and remains rotatably connected.

[0008] Preferably, the axis between the inner wall of the separation tank and the two rotating rods above the separation tank is inclined, and its inclination is consistent with the inclination of the filter screen.

[0009] Preferably, a drive device is also provided outside the separation tank, and the drive device maintains transmission with any one of the rotating rods.

[0010] Preferably, a slot is provided on the wall of the separation tank, and the slag discharge trough plate is inserted into the slot, with the top of the slag discharge trough plate not higher than the top of the filter screen plate.

[0011] Preferably, the slag discharge trough plate is disposed at the end of the filter screen plate away from the filter surface and is in contact with the filter screen plate.

[0012] Preferably, the cleaning mechanism is disposed between the filter screen plate and the slag discharge trough plate, with the slag discharge trough plate located below the top of the cleaning mechanism.

[0013] Compared with the prior art, the present invention has the following advantages: 1. Achieve continuous filtration and separation, breaking the bottleneck of production interruption. This device, by incorporating an inclined filter screen and a rotating cleaning mechanism within the separation tank, allows for filter screen cleaning during the filtration process without requiring system shutdown. The cleaning mechanism continuously scrapes solids or suspended matter from the filter screen surface upwards, which are then collected and discharged directly by the slag discharge trough at the outlet. This completely avoids process interruptions caused by solid matter deposition, ensuring continuous liquid filtration and separation, and effectively meeting the continuity requirements of industrial production processes.

[0014] 2. Stabilize filtration efficiency and accuracy, reducing the risk of performance degradation. In existing technologies, solid matter clogging of the filter screen leads to a reduction in flow area and an increase in filtration resistance, resulting in decreased efficiency and fluctuations in accuracy. This device, through real-time slag removal by the cleaning mechanism, keeps the filter screen pores unobstructed at all times. This not only prevents the filtration rate from decreasing due to clogging but also ensures the consistency of the filter screen's interception accuracy, guaranteeing the stable purity of the filtered liquid and reducing quality risks in subsequent processes.

[0015] 3. Reduce labor and maintenance costs, and improve overall production efficiency. This device eliminates the need for staff to periodically disassemble and manually clean the filters, significantly reducing labor input and operational complexity. Simultaneously, the continuous operation mode minimizes production losses due to downtime for maintenance, improving equipment utilization and overall production efficiency. Furthermore, the slag discharge trough prevents cleaned solids from flowing back into the separation tank, eliminating the need for secondary treatment and further reducing processing costs in subsequent stages.

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0018] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0019] As described in the background section, existing liquid filtration and separation devices cannot remove solids when filtering liquids, resulting in solids constantly accumulating on the filter screen, which reduces filtration efficiency. Regular manual cleaning of the solids is required for continued use, which is quite inconvenient.

[0020] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 8 This utility model provides a liquid continuous filtration and separation device, including a separation tank 1, with an inlet pipe 2 connected to the bottom of one end and a drain pipe 8 connected to the bottom of the other end; The filter screen 10 is inclinedly disposed in the separation tank 1 and in contact with the bottom of the separation tank 1. The cleaning mechanism rotates and is located at the outer end of the filter surface of the filter screen plate 10 while maintaining its top extension above the separation tank 1; The slag discharge trough plate 7 is set on the outside of the discharge end of the cleaning mechanism and fixed on the separation tank 1.

[0021] In this embodiment, the cleaning mechanism includes a rotating rod 9 that is rotatably mounted on the inner wall of the separation tank 1 and parallel to the upper part of the separation tank 1. A transmission belt 3 is sleeved on the outer end of the rotating rod 9. Several support plates 4 are evenly spaced on the outer end of the transmission belt 3. The outer end of the support plates 4 is close to the filter screen plate 10. Filter holes are evenly opened on the support plates 4.

[0022] As mentioned above, setting up a support plate can facilitate the upward scraping of solids or suspended matter accumulated on the filter screen, thereby preventing accumulation. Setting up water filter holes can prevent the liquid from being scraped up when it is scraped upward, thus preventing some of the liquid from falling into the slag discharge trough plate.

[0023] In this embodiment, a support base 5 is fixed above the wall of the separation tank 1, and the rotating rod 9 passes through the support base 5 and remains rotatably connected.

[0024] In this embodiment, the axis between the inner wall of the separation tank 1 and the two rotating rods 9 above the separation tank 1 is inclined, and its inclination is consistent with the inclination of the filter screen plate 10.

[0025] As mentioned above, setting the inclination of the axis between the rotating rods to be consistent with the inclination of the filter screen plate is to facilitate the outer support plate of the transmission belt to scrape the solids accumulated at various positions of the filter screen plate upward during the rotation of the transmission belt, thus avoiding local clogging of the filter screen plate.

[0026] In this embodiment, a drive device 6 is also provided outside the separation tank 1, and the drive device 6 maintains transmission with any one of the rotating rods 9.

[0027] Please see the appendix Figure 7 In this embodiment, a slot is provided on the wall of the separation tank 1, and the slag discharge trough plate 7 is inserted into the slot. The top of the slag discharge trough plate 7 is not higher than the top of the filter screen plate 10.

[0028] In this embodiment, since the cleaning mechanism may be located on the inclined side or bottom side of the filter screen, please refer to the attached document carefully. Figure 5 When the cleaning mechanism is on the inclined side of the filter screen plate, the slag discharge trough plate 7 is located at the end of the filter screen plate 10 away from the filter surface and is in contact with the filter screen plate 10.

[0029] Please see the appendix Figure 8 When the cleaning mechanism is located on the bottom side of the filter screen plate, the cleaning mechanism is positioned between the filter screen plate 10 and the slag discharge trough plate 7, with the slag discharge trough plate 7 located below the top of the cleaning mechanism.

[0030] As described above, when the cleaning mechanism is located on the bottom side of the filter screen, the positions of its inlet pipe and outlet pipe are switched so that the cleaning mechanism is always on the filter surface of the filter screen to clean the filter surface.

[0031] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
